Association of Connective Tissue Grafts in Immediate Implants: Systematic Review and Meta-Analysis.

BACKGROUND: The increase in soft tissue (ST) around implants can benefit peri-implant health and aesthetic results. The objective was to compare the gingival and esthetic health benefits of immediate implant placement (IIP) with simultaneous or delayed connective tissue graft (CTG) compared to IIP without CTG. METHODS: A systematic review was carried out by two reviewers in Medline-Pubmed, Scopus, and Cochrane. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were considered. Randomized Clinical Trials (RCTs) that were published between April 2017 and February 2024 were used. Studies that analyzed the performance of a simultaneous or deferred CTG after the placement of an implant in the aesthetic zone, with or without immediate provisionalization, without previous regeneration, with a follow-up of 6 months, and that were performed in humans were included. RESULTS: Quantitative analysis was performed using data provided by the RCTs. The five RCTs that were selected analyzed a total "n" of 245 subjects who met the inclusion criteria and focused on the subject of the study. In the quantitative analysis, four RCTs were included. The studies evaluated buccal gingiva levels when placing the IIP with and without CTG, obtaining a mean buccal gingiva level difference of 0.09 mm (95% CI: -0.54 to 0.72, p = 0.05), statistically not significant, but with a favorable trend. CONCLUSIONS: The use of CTG associated with the II can maintain the gum level but not increase the volume. CTG is favorable for achieving successful esthetic results when immediate placement of an implant with a provisional prosthesis is planned.

Role adoption, anxiety, depression and loneliness in family caregivers of patients with chronic diseases.

OBJECTIVE: to describe and explore the relationship of loneliness, anxiety and depression with adoption of the caregiver role among individuals caring for people with chronic diseases in Colombia. METHODS: this was an exploratory and cross-sectional study involving 960 primary caregivers of individuals with chronic diseases. We applied the Caregiver Role Adoption Scale, the University of California at Los Angeles Loneliness Scale, and the Anxiety and Depression Scale. Principal component and multiple correspondence analyses were performed for clustering. RESULTS: among the participating caregivers, 40.8% reported experiencing depression, 59% reported anxiety, 54.6% reported moderate to severe loneliness, and 88.6% reported satisfactory adoption of the caregiver role. Caregivers who presented basic or insufficient role adoption levels tended to have higher scores for anxiety, depression and loneliness. CONCLUSION: adoption of the caregiver role is a mediator in the anxiety, depression and loneliness levels among caregivers. Strategies aimed at supporting caregivers should include training for the caregiver role to mitigate the negative impacts of anxiety, depression and loneliness. (1) More than half of the caregivers reported moderate or severe anxiety and loneliness. (2) Caregivers with low role adoption levels presented more anxiety, depression and loneliness. (3) Satisfactory adoption of the caregiver role reduces anxiety, depression and loneliness. (4) Role adoption should be intervened to reduce the impact on caregivers' mental health.

Comparative Analysis of Quality of Life of Family Caregivers of Patients With Heart Failure and Cancer Who Receive Palliative Care.

BACKGROUND: Quality of life (QoL) is the criterion-standard outcome in palliative care for patients with various illnesses and their family caregivers. There is a need to determine the factors affecting caregivers' QoL in each population and the differences between groups to design differentiated intervention strategies. PURPOSE: The aims of this study were to compare the role adoption, social support, and QoL of family caregivers of patients with heart failure and cancer in palliative care and to examine the determinants of QoL. METHODS: A comparative study was conducted with the family caregivers of patients with cancer (n = 81) and heart failure (n = 80) in palliative care. Quality of life in life-limiting situations, role adoption, and social support questionnaires were also administered. A χ2 test, Student t test, and Mann-Whitney U test were used for between-group comparisons. Multiple linear regression was used to examine the effects of the correlated variables on caregivers' QoL. RESULTS: Caregivers of patients with heart failure had better QoL (P = .006) and lower tangible social support (P = .007) than caregivers of patients with heart failure. No differences were found in caregiver role adoption between the groups. Linear regression indicated that for caregivers of patients with cancer, social support, role adoption, caregiver age, and patient functional status affect caregiver QoL. For caregivers of patients with heart failure, role adoption and patient functional status are predictors of QoL. CONCLUSIONS: Overall, healthcare professionals should focus on improving social support and caregiver role adoption and provide greater attention to the QoL of caregivers of patients with cancer.

The Accuracy of Bone Assessment Distal to Lower Second Molars Using Panoramic Radiography: A Systematic Review and Meta-Analysis.

Panoramic radiography (OPG) evaluates mandibular third molar impaction (MTMI). This systematic review aimed to investigate the diagnostic accuracy of OPG in detecting bone loss distal to the lower second molars. The associated bone loss with different impaction positions and the most prevalent positions of MTMI were investigated as secondary outcomes. In January 2023, PubMed, Scopus, and Cochrane were searched to identify studies published between January 2012 and January 2023. Two examiners blindly selected the eligible studies for data extraction and quality assessment. Of 427 studies, 8 were suitable for data extraction. All studies reported bone loss distal to the second molar using OPG, ranging from 4.9 to 62.9%. The most frequent position of MTMI is mesioangular. The distal bone loss in the vertical and horizontal positions is statistically significant compared to typically positioned third molars and those that are fully erupted or impacted, but in a normal orientation (p-value 0.005 and 0.02, respectively). Bone loss was not statistically significant in the mesioangular position compared to other impacted positions (p-value 0.14). The risk of bias ranges between 66 and 88%. Despite its limitations, OPG is still considered a valuable tool to assess bone loss distal to the lower second molar in cases of an impacted mandibular third molar.

Genetic modifiers of cognitive decline in PSEN1 E280A Alzheimer's disease.

INTRODUCTION: Rate of cognitive decline (RCD) in Alzheimer's disease (AD) determines the degree of impairment for patients and of burden for caretakers. We studied the association of RCD with genetic variants in AD. METHODS: RCD was evaluated in 62 familial AD (FAD) and 53 sporadic AD (SAD) cases, and analyzed by whole-exome sequencing for association with common exonic functional variants. Findings were validated in post mortem brain tissue. RESULTS: One hundred seventy-two gene variants in FAD, and 227 gene variants in SAD associated with RCD. In FAD, performance decline of the immediate recall of the Rey-Osterrieth figure test associated with 122 genetic variants. Olfactory receptor OR51B6 showed the highest number of associated variants. Its expression was detected in temporal cortex neurons. DISCUSSION: Impaired olfactory function has been associated with cognitive impairment in AD. Genetic variants in these or other genes could help to identify risk of faster memory decline in FAD and SAD patients.

Terpyridine isomerism as a tool for tuning red-to-NIR emissive properties in heteronuclear gold(I)-thallium(I) complexes.

The polymeric linear chain [AuTl(C6Cl5)2]n reacts with three terpyridine-type ligands substituted with thiophene groups containing N-donor centres in different relative positions (L1, L2 and L3), leading to the Au(I)/Tl(I) complexes [AuTl(C6Cl5)2(L1)]n (1), [{AuTl(C6Cl5)2}2(L2)]n (2) and [AuTl(C6Cl5)2(L3)]n (3). X-Ray diffraction studies reveal that L1 acts as a chelate, while L2 and L3 act as bridging ligands, resulting in different coordination indexes for the thallium(I) centre. These structural differences strongly influence their optical properties, and while compounds 2 and 3 emit near the limit of the visible range, complex 1 emits in the infrared region. DFT calculations have also been carried out in order to determine the origin of the electronic transitions responsible for their optical properties.

Mandibular Third Molar Impaction and Bone Change Distal to the Second Molar: A Panoramic Radiographic Study.

Background: The mandibular third molar is the most frequently impacted tooth. An impacted mandibular third molar (IMTM) can have negative consequences on the adjacent mandibular second molar (MSM), such as bone loss. An IMTM can be identified using orthopantomography (OPG). Our objective is to compare changes in bone level distal to the mandibular second molar (MSM) in patients with an extracted IMTM versus non-extracted IMTM using OPG. Methods: In this retrospective case-control study, 160 orthopantomograms (OPGs) of 80 patients who attended Dental Hospital of the University of Barcelona (HOUB) were randomly selected. Participants were stratified into a study group and control group. Results: Males and females experienced bone gain in the study group and bone loss in the control group. However, the difference in bone-level change was not statistically significant regarding gender in the study group. Within the study group, the age group of 29-39 years demonstrated significant (p-value = 0.042) bone gain after extraction compared to other age groups. However, the control group demonstrated bone loss in all age groups in which the difference is not statistically significant (p-value 0.794). Conclusions: Bone improvements distal to the MSM were observed after the extraction of an IMTM compared to when an IMTM was not extracted.

Implementation of a coaching training for enhancing empathy and emotional intelligence skills in health science students: a prospective study.

BACKGROUND: Empathy and emotional intelligence are core competencies in the educational curriculum of health science students, both play a significant role in teamwork relationships and in attention patient's cares; so innovative strategies to enhance these emotional skills are required. We prospectively tested an academic coaching program for improving empathy and emotional intelligence in students of health sciences degrees. METHODS: A prospectively single arm intervention study was performed in undergraduate students of nursing, physiotherapy and occupational therapy of the Faculty of Health Sciences from the University of Granada (Spain). The three groups of students participated in nine sessions of coaching, which included a training program to manage patient's priorities and communication, adherence to treatment, motivation and satisfaction. Survey data included the Cognitive and Affective Empathy Test (TECA), the Trait Meta-Mood Scale (TMMS-24) and the Interpersonal Reactivity Index (IRI) which were assessed at baseline and post-intervention. RESULTS: A total of 93 students of 259 (mean age of 21.6 ± 3.2 years) participated in the study and completed the sessions of coaching/surveys. After the intervention, we observed an improvement in the cognitive dimension of empathy among nursing students (p = 0.035) and in the affective dimension of empathy in physiotherapy students (p = 0.044). In addition, an increase on perceived emotional intelligence among students was achieved only in nursing/physiotherapy groups (p ≤ 0.048). Finally, slight improvements were founded in the dimensions "Perspective-Taking" and "Personal Distress" of the occupational therapy group (p ≤ 0.031). No significant differences were found for the rest of variables of TECA (p ≥ 0.052), TMMS-24 (p ≥ 0.06) and IRI (p ≥ 0.12). CONCLUSIONS: This study shows that an academic coaching intervention with students from health sciences degrees improves their empathy skills and self-perceived emotional intelligence. The current findings can be used to determine more effective approaches to implementing academic coaching interventions based in better designs as clinical trial studies.

Soledad, ansiedad, depresión y adopción del rol del cuidador de personas con enfermedad crónica en San Gil, Colombia

Introducción: Los cuidadores de personas con enfermedad crónica adoptan un nuevo rol que puede implicar respuestas como ansiedad, depresión y soledad. Objetivo: Describir y correlacionar las variables de adopción del rol del cuidador, depresión, ansiedad y soledad en cuidadores familiares de personas con enfermedad crónica en la provincia de Guanentina, en San Gil, Santander (Colombia), durante el año 2021. Método: Estudio descriptivo, analítico de corte transversal realizado con 112 cuidadores familiares de personas con enfermedades crónicas. Se utilizó una ficha de caracterización y los instrumentos: Escala adopción del rol del cuidador ROL, escala de soledad de UCLA (University of California at Los Ángeles) y Escala Hospitalaria de Ansiedad y Depresión HADS. Resultados: El perfil de los cuidadores fue predominantemente mujer; de 49 años en promedio; casadas, solteras o en unión libre; grado máximo de escolaridad bachiller; de ocupación hogar y nivel socioeconómico medio bajo y bajo. Se encontraron niveles altos de ansiedad en el 18,3 % de ellas, depresión en el 4,3 % y soledad en el 0,9 %, además, se evidenciaron niveles de adopción del rol del cuidador satisfactorios en el 100 %. Se encontró una correlación débil entre ansiedad, depresión y soledad y una correlación inversa entre estas variables con la adopción del rol del cuidador. De igual manera, se encontró una correlación directa entre la edad del paciente y los meses de diagnóstico con las horas de cuidado al día. Por último, se halló carácter predictivo de la ansiedad y la depresión sobre la adopción del rol, de la ansiedad y la adopción del rol sobre la depresión, y de la soledad y la depresión sobre la ansiedad. Conclusiones: los cuidadores tenían niveles de ansiedad, depresión y soledad normales que, al correlacionarse entre sí y con la adopción del rol del cuidador, validan la idea de que, si se interviene a los cuidadores en su trayectoria con orientaciones sobre su rol en cuanto a las labores, la organización y las respuestas se puede contribuir en la disminución de la ansiedad, depresión y soledad. Discusión: la correlación directa observada entre la soledad, depresión y ansiedad es coherente con lo reportado en estudios previos con cuidadores. Acorde con lo reportado por la literatura el desempeño satisfactorio del rol facilita los desenlaces en los cuidadores, en este caso, la moderación de la ansiedad, depresión y soledad.

Introduction: Caregivers of people with chronic disease adopt a new role that may involve responses such as anxiety, depression, and loneliness. Objective: To describe and correlate the variables of adoption of the role of caregiver, depression, anxiety and loneliness in family caregivers of people with chronic disease in the Guanentina province in San Gil, Santander (Colombia), during the year 2021. Methods: Descriptive study, cross-sectional analysis carried out with 112 family caregivers of people with chronic diseases. A characterization sheet and the ROL, UCLA and HADS instruments were used. Results: the profile of the caregivers was predominantly female and average age of 49 years; married, single or in civil union; maximum degree of high school education; of household occupation and low and low-middle socioeconomic level. High levels of anxiety were found in 18,3% of them, depression in 4,3% and loneliness in 0,9%, in addition, satisfactory levels of adoption of the caregiver role were evidenced in 100%. A weak correlation was found between anxiety, depression and loneliness and an inverse correlation between these variables with the adoption of the caregiver role. Similarly, a direct correlation was found between the patient's age and the months of diagnosis with the hours of care per day. Finally, anxiety and depression were found to be predictive of role adoption, of anxiety and role adoption on depression, and of loneliness and depression on anxiety. Conclusions: the caregivers had normal levels of anxiety, depression and loneliness that, when correlated with each other and with the adoption of the caregiver role, validate the idea that, if caregivers are intervened in their trajectory with guidance on their role in terms of the tasks, the organization and the answers can contribute in the reduction of anxiety, depression and loneliness. Discussion: The direct connection observed between loneliness, depression and anxiety is consistent with what has been reported in previous studies with caregivers. In accordance with what has been reported in the literature, satisfactory performance of the role facilitates the outcomes in caregivers, in this case, the moderation of anxiety, depression and loneliness.

PALLIATIVE CARE AND END OF LIFE CARE IN LATIN AMERICA: SCOPING REVIEW

INTRODUCTION: Populational aging and improved treatments for chronic non-communicable diseases extend life expectancy but not always quality of life. By 2060, 48 million people are expected to die of serious illnesses, and 83% of these deaths will occur in developing countries. Only 14% of those who needed palliative care receive it. AIM: To describe the methodological trends, thematic areas, populations studied, and future challenges in Latin American regions with respect to adult palliative care. METHODS: A scoping review of 60 articles from 2010 to 2019 in indexed journals in English, Spanish, and Portuguese was conducted. RESULTS: Most articles were from Brazil, Colombia, and Mexico. Patients, caregivers, healthcare professionals, and students constituted the primary study population. Quality of Life, knowledge, and costs of attention were also assessed. It appears that early palliative care improves the outcomes of patients, caregivers, and health care professionals, however, the disparity in palliative care services between Latin America, US, UK, Canada, and Spain is concerning. CONCLUSIONS: Globally, more palliative care is needed, especially in Latin America. However, there are not enough graduate palliative care programs. Academic palliative care education must be promoted. Communication between the interdisciplinary team, the patient, and the caregiver is critical. While the region's scientific literature output has improved, many knowledge gaps remain. For patients' sake, governments should regulate, create, and facilitate palliative care services.

Vapochromic behaviour of a gold(I)-lead(II) complex as a VOC sensor.

The reaction among [Au2Ag2(C6F5)4(OEt2)2]n, PbCl2 and terpyridine leads to the polymeric complex [{Au(C6F5)2}2{Pb(terpy)}]n (1). Its crystal structure reveals potential voids close to the lead centres large enough to hold different molecules. The availability of these free sites allows complex 1 to act as a VOC sensor. Thus, when 1 is exposed to different solvent vapours such as acetonitrile, toluene or THF, variations in its solid appearance and its photophysical properties are observed as a consequence of the formation of the new polymorphs [{Au(C6F5)2}2{Pb(terpy)(CH3CN)2}]n (2), [{Au(C6F5)2}2{Pb(terpy)}]n·Tol (3) and [{Au(C6F5)2}2{Pb(terpy)(THF)}]n·THF (4). Each polymorph displays a different emission energy depending on its structure and the presence of metallophilic interactions. In addition, the reversible solvent molecule exchange allows the tuning of the luminescence emissions in the greenish yellow-red range. DFT and TD-DFT calculations were performed to explain the origin of the luminescence of all these complexes.

The prevalence of elongated styloid process in the population of Barcelona: a cross-sectional study & review of literature.

BACKGROUND: Styloid process (SP) is a cylindrical bony projection that originates from the inferior part of the petrous temporal bone just anteriorly to the stylomastoid foramen. Several nerves, muscles, and ligaments are related closely to the (SP). It is considered elongated when the measurement exceeds 30 mm. The overall prevalence of the styloid process is between 3.3% to 84.4%. The elongation of the styloid process (ESP) is associated with the manifestation of Eagle's Syndrome (ES) which is characterized by various types of pain in the head and neck region such as headache, tinnitus, otalgia, and trigeminal neuralgia. Eagle's syndrome occurs in 4-10.3% of individuals with an elongated styloid process (ESP). The objective of the study is to determine the prevalence of (ESP) in the patients who were treated in the Dental Hospital University of Barcelona (HOUB), to review the literature to spot the light on the different demographic data worldwide. METHODS: The archived panoramic image in the University of Barcelona dental Hospital were consecutively retrieved to investigate the prevalence of (ESP). Of all digital panoramic radiographs (OPG), 400 met the inclusion criteria and were furtherly analyzed. The results are correlated with the participant's gender, age, and occurrence. Age is subcategorized into three groups. A chi-square test is used to measure the significant differences and the P-value is set at < 0.05 for the level of significance. RESULTS: Among the included 400, we found 291 demonstrating (ESP). The prevalence of (ESP) which exceeds 30 mm is 72.75%. It is found that the most common morphological type is type 1 which is regarded as the uninterrupted (ESP) regardless of gender and age group. Concerning the calcification pattern, the most prevalent is the partial calcified (ESP) despite genders and age groups. CONCLUSION: (OPG) is a sufficient tool for the screening of the elongated styloid process. Regarding the prevalence, our results are considered higher than previously reported prevalence in different populations using (OPG) radiography tool. A study on a wider spectrum of the Spanish population is recommended to further investigate the correlation between the elongated styloid process and the occurrence of Eagle's syndrome.

Role of selected salivary inflammatory cytokines in the diagnosis and prognosis of oral squamous cell carcinoma. A Systematic Review and Meta-analysis

Background: Oral squamous cell carcinoma (OSCC) is gradually increasing its incidence in our society. Unfortunately, this entity is diagnosed at an advanced stage in most patients, a fact that implies greater difficulty in its treatment and a worse prognosis. This systematic review aims to assess whether the cytokines IL-6, IL-8 and TNF-α are potential salivary biomarkers that allow early diagnosis of cancer. Material and methods: An electronic search was performed in three databases (Pubmed, Scopus and Web of Science). We used the following keywords: "salivary cytokines", "saliva cytokines", "salivary interleukins", "biomarkers", "oral squamous cell carcinoma" and "diagnosis", combined with the Boolean operators "AND" and "OR". Results: 128 publications were found and finally 23 articles were included in the review and 15 in the meta-analysis. It has been observed that the majority of OSCC patients express higher salivary concentrations of IL-6, IL-8 and TNF-α compared to the control (CL) and premalignant lesion (OPML) groups. It has also been observed that the different premalignant lesions do not have statistically significant differences in the salivary concentration of the cytokines, and on the other hand, differences have been observed between the different TNM stages. The meta-analysis has shown that the difference in concentration of IL-6, IL-8 and TNF-α is statistically significant between the CL group and the OSCC, and also between the CL group and OPML. Conclusions: There is sufficient evidence to affirm that IL-6, IL-8 and TNF-α are useful salivary cytokines in the early diagnosis and prognosis of OSCC. Although future studies are necessary to establish greater reliability of these biomarkers and thus be able to develop a valid diagnostic test. (AU)

Deciphering the Primary Role of Au⋠⋠⋠H-X Hydrogen Bonding in Gold Catalysis.

Au⋅⋅⋅H-X (X=N or C) hydrogen bonding is gaining increasing interest, both in the study of its intrinsic nature and in their operability in different fields. While the role of these interactions has been studied in the stabilization of gold(I) complexes, their role during the minimum free energy reaction pathway of a given catalytic process remains unexplored. We report herein that complex [Au(C≡CPh)(pip)] (pip=piperidine) catalyses the A3 -coupling reaction for the synthesis of propargylamines, thanks to the ability of Au(I) to promote weak hydrogen bonding interactions with the reactants along the free energy profile. Density Functional Theory (DFT) calculations show that these Au⋅⋅⋅H-X interactions play a directing role in the catalysed A3 -coupling. Topological non-covalent interactions (NCI), interaction region indicator (IRI) and quantum theory of atoms in molecules (QTAIM) analysis in real space of the electron density provide a description of these interactions accurately.

X-Chromosome Association Study in Latin American Cohorts Identifies New Loci in Parkinson's Disease.

BACKGROUND: Sex differences in Parkinson's disease (PD) risk are well-known. However, the role of sex chromosomes in the development and progression of PD is still unclear. OBJECTIVE: The objective of this study was to perform the first X-chromosome-wide association study for PD risk in a Latin American cohort. METHODS: We used data from three admixed cohorts: (1) Latin American Research consortium on the Genetics of Parkinson's Disease (n = 1504) as discover cohort, and (2) Latino cohort from International Parkinson Disease Genomics Consortium (n = 155) and (3) Bambui Aging cohort (n = 1442) as replication cohorts. We also developed an X-chromosome framework specifically designed for admixed populations. RESULTS: We identified eight linkage disequilibrium regions associated with PD. We replicated one of these regions (top variant rs525496; discovery odds ratio [95% confidence interval]: 0.60 [0.478-0.77], P = 3.13 × 10-5 replication odds ratio: 0.60 [0.37-0.98], P = 0.04). rs5525496 is associated with multiple expression quantitative trait loci in brain and non-brain tissues, including RAB9B, H2BFM, TSMB15B, and GLRA4, but colocalization analysis suggests that rs5525496 may not mediate risk by expression of these genes. We also replicated a previous X-chromosome-wide association study finding (rs28602900), showing that this variant is associated with PD in non-European populations. CONCLUSIONS: Our results reinforce the importance of including X-chromosome and diverse populations in genetic studies. © 2023 The Authors.
